SPECIFIGATION forming part of Letters Patent No. 547,597, dated October 8, 1895.

Application filed February 14, 1895. Serial No. 533.331. (No model.) I

Be itknown that I, ALLEN C. BRANTIN HAM, a citizen of the United'States, residing at T0- I ledo, in the county of Lucas and State of Ohio,

have invented certain new and useful Improvements in Grain Heaters and Steamers,

of which the following is a specification.

The object'of my presentinvention is to produce an efiicient grain heater and steamer elevation; Fig. 2, a horizontal sectional view looking downwardly from the dotted line 2 2 in Fig. 1; Fig. 3, adotailvicw, on an enlarged scale, as seen from the dotted line-o S in Fig.- 4; and'hig. 4, a detail horizontal sectional view looking downwardly from .the dotted line l 4 in Fig. 3. V

In said drawings the portionsmarked A represent the casing of my improved heater; B, the driving-shaft thereto; C, the shaftwhich extends vertically through saidheater, and D general outline and contains severalhopper- I a steam-pipe which enters said heater, through which moisture and heat are supplied thereto. The casingA is preferably cylindrical in shaped portions A A A A? and terminates at the bottom in the hopper-shaped portion A. Access is'provided to the chambers or open spaces between said hoppers and the interior surface of the cylindrical casing by means of openings formed in'the side's ofs'aid casing, and which are provided with covers or stoppers le fivhioh are generally and prefer- "ahly securedjin' placebybolts of, having appropriate adjustable engaging-arms c. The,

' walls of the heater are preferably made doubio and packed with some substantially none heat-conducting materiahas shown; for the purpose of maintaining substantial uniformity of temperature in the interior of said heater. Entering or connected wi'tha perfo ration in the top A is an egress'spont'A through which the grain'is introduced into the heater.

The lower hopper A is provided with an adjustable ring R, which forms an extensionto the nozzle of discharging point therefor, and which is screw-threaded and passes over the ordinary fixed nozzle or discharging point.v

This ring R reaches down to the desired dis- 7 tance from the disk 0 and the size of the bevel-pinion b, which engages with a cone spending bevcl-pinion-c on the upper end. of the shaft 0.

The shaft 0 is mounted vertically in suitable bearings in the bridge-trees T and T at the top and bottom of the heater structure, respectively, and is driven by the gears already described from the driving-shalt B. It

carries a disk 0', which is fixedly mounted thereon, a disk 0 which is so mounted as to be revolvedby, the shaft, but free to move longitudinally of the shaftfand the winged head 0 through which thelongitudinal movement of the dislcC is secured, as will be pres-j.v ently more fully described. Tho"'disk C re ceives the discharge of grain from the first hopper A, andsaid grain is spread out over and discharged from said dislr'by centrifn gal force, as will be readily. understood, and

thence falls into the hopperx. From the hopper A it descends onto thedisk O, which imparts a similar movement toit, and it thence falls into thehopper A and thence downpast -the winged hub O to the hopper A whence itdischarges finally onto the disk 0 which.
